An Interpretation Method of One-dimensional Joint Inversion Based on TEM and CSAMT

Joint inversion is an important development direction of geophysical data interpretation. In this paper, on condition of emission by the horizontal electric dipole, fast Hankel transform is used to calculate level electric field response of one-dimensional horizontal layered earth in CSAMT modeling, while G-S transform is used in for TEM modeling. In the basis of one-dimensional forward, joint inversion method is established based on generalized inverse, theoretical model inversion results show that joint inversion method is better than a single inversion.
